On Monday, the memorial was opened to the public. New York City Mayor Michael Bloomberg was on hand to welcome the first visitors.

“New Yorkers, Americans and people around the world now have a beautiful, dignified place to pay tribute to the memory of the 2,983 men, women and children we lost in the tragic attacks of 9/11,” he said.

As you would expect, a lot of people want to get a glimpse of the memorial. Over 7,000 came with tickets to visit the memorial. The tickets are free, but reservations are required to enter the new space.

People that showed up without tickets were turned away.

The demand to visit the site and pay respects is high. According to the WSJ, 400,000 people have signed up online to visit the memorial in the next few months.

The memorial features 2,983 names in bronze panels, all encasing 30-foot waterfalls. It’s a truly inspiring piece of design.

But one family has an issue with the memorial, as they discovered on Sunday that the name of their loved one had been misspelled on the memorial.

Jeffrey Schreier was one of 658 people from the brokerage firm Cantor Fitzgerald to die in the WTC attacks. When his sister found his name on the memorial on Sunday, she saw that it read “Jeffery” instead of “Jeffrey.” The second E and the R had been switched.

Schreier’s brother-in-law David Hart had this to say, as reported by MSNBC:

“As I was looking at the name, all of a sudden, I realized this name was not quite spelled correctly.”

“You feel as though Jeffrey’s soul is now looking down and saying, ‘Can’t you get my name right?’”

The spokesman for the memorial has indicated that they are working to correct the error.

I can surely understand how an error like this could affect a grieving family. In a memorial with nearly 3,000 names, I wonder if there are any other errors that have yet to be discovered.

During the afternoon game between the Washington Redskins and the New York Giants, the league participated in the tribute to the victim of 9/11. A video of a solider playing “Taps” was the background for flag unveilings all around the NFL. The Redskins – Giants game was seen as the 9/11 tribute game, as the two teams represent the two major cities affected by the attacks.

This video was seen by everyone watching the game yesterday –

Flickr and Instagram have immortalized the day with some beautiful photo collections:

News Corp’s The Daily – its iPad magazine has put together a slideshow for 9/11 in photos.

YouTube partnered with the New York times for a dedicated channel, and has selected a couple of handpicked videos to share on their own blog.

Singing from Ground Zero, Simon’s lyrics resonated with the crowd, and you can see the emotion on their faces as well as Simon’s. A truly touching tribute to everyone that had their life changed by the events of 9/11.

Here are the details:

New Jersey September 11th Memorial
Located in New Jersey’s Liberty State Park, “Empty Sky” New Jersey 9/11 Memorial remembers 746 magnificent New Jersey lives lost on September 11th, 2001. As people gathered at the Hudson River to witness the event, organize rescue efforts and then remember and mourn, they found strength in their community. “Empty Sky” honors the memory of those lost and the special place they called home while framing the view where the Towers once stood. The 746 names are engraved on the twin 210-foot long (the width of each side of the World Trade Center) brushed stainless steel walls that face one another and rise 30 feet in height. Like the World Trade Center, the stainless steel reflects the constantly changing light of day. The memorial invites visitors to literally and metaphorically look toward the empty sky in memory of their loved ones and look forward as a community.

Westchester September 11th Memorial
To honor the 112 magnificent people from Westchester County who perished that day, 112 intertwined stainless steel DNA-like strands rise 80 feet from the ground reaching upward to the heavens to form “The Rising.” The strands are bound together in a literal and symbolic gesture exemplifying the strength of the Westchester community and the families who lost loved ones. Forming an unbroken circle, the 112 individual strands emerge from the existing footprint on the plaza. The memorial’s visual lightness acts as a counterpoint to the solidity of the adjacent Kensico Dam. “The Rising” invites visitors to walk around and through it from all directions and allows persons of all ages and abilities to move through it and experience it close-up.

This weekend, both will be featured in dedication ceremonies. On Saturday at 11Am, there will be one at Liberty State Park for the first one.

For the second, there will be one at the Westchester County September 11th Memorial at 6:00PM.

Over 5,000 flags and banners are being flown during the three day event, which is already in progress.

Flags can be purchased for $25 to honor a fallen soldier.

“The Field of Flags Memorial has already received an astonishing show of encouragement from the Salem business community,” said Jerry Thompson, coordinator for the event. “We are so grateful for the generous support without which we would not be successful. This memorial is so important, and these contributions demonstrate how committed this nation is to honoring the victims of 9/11 and our troops.”

Additional Patriot Day events will be held throughout the weekend, including a cannon salute, a military flyover and a Run-to-Remember 5k race, with proceeds benefiting E.S.C.A.P.E’s Child Abuse Prevention Program and the Oregon Military Emergency Relief Fund.

NASA has a Remembering September 11th post up on their official site today, and the most compelling part of it deals with 9/11 as seen from space.

The image above was taken by the Landsat 7 satellite with the Enhanced Thematic Mapper Plus on September 12th, 2001. The day after 9/11, you can still see the smoke and debris billowing from Ground Zero.

Another interesting aspect of the story is astronaut Frank Culbertson, the only American not on planet Earth when the attack occurred. He was actually high above the Earth aboard the International Space Station.

As the attacks went down, Culbertson was passing over the NYC area. On the morning of September 11th, he took out his camera and snapped the photo seen below –

“The smoke seemed to have an odd bloom to it at the base of the column that was streaming south of the city. After reading one of the news articles we just received, I believe we were looking at NY around the time of, or shortly after, the collapse of the second tower. How horrible,” he said in a public letter written on that day.

We can only imagine what it felt like on that tragic day to watch it all happen from space.

WebProNews has an interesting video discussing this with Dr. Farshid Delgosha, a professor at the New York Institute of Technology, who says, ““Now, because of the widespread usage of the Internet and the Web and the great deal of information and sensitive information that exists on the Web, definitely that [cyber] is the battleground in the future.”

WebProNews also ran another story in June, talking with Charles Dodd, a U.S. government consultant on cyber defense, who said, “Cyber will be the next generation warfare.”

This week, an online security bill was introduced in Senate.

The Today Show’s Matt Lauer takes a trip to the construction site of the new Freedom Tower, or 1 World Trade Center. He talks to the architect of the building, discussing the structural differences between the new tower and the old World Trade Center Towers.

They make their way to the current top floor, the 76th, and we get some great shots of what NYC will look like from the top.

When completed, the tower will reach 1776 feet to the top spire.
